BCH4024 060925 OC Su25 E1 Q36: Enolase catalyzes the conversion of 2-phosphoglycerate to phosphoenolpyruvate using metal-ion catalysis. What statement best describes the role of the Mg2+ in this reaction?

BCH4024 060925 OC Su25 E1 Q48: Fatty acids (FAs) and Triacylglycerols (TAGs) are classes of lipids that play an important role in energy storage in eukaryotic organisms. The hydrocarbon chain in the tail region of both FA and TAG can be saturated or unsaturated. The degree of saturation will determine their melting point. Which statement about TAG and FA is correct?

BCH4024 060925 OC Su25 E1 Q8: Histidine is a unique amino acid that has several functions in mammalian cells. The properties of His are associated with its pI under physiological conditions. Indicate the location of the nitrogen on the side chain of Histidine. Also calculate the pI of Histidine given the following pKa values.

BCH4024 060925 OC Su25 E1 Q2: Water has numerous biochemical properties in living systems. These properties include its ability to solubilize polar substances, and to disassociate into hydronium and hydroxide ions. When amphipathic molecules interact with water, they form micelles. Provide an explanation for the stabilization of micelles in water?

BCH4024 060925 OC Su25 E1 Q31: A researcher attempts to compare the Kcat/Km of three different enzymes (A-C), in order to determine the catalytic efficiency of the enzymes in the presence of multiple different substrates.
